What does manic mean?
Manic describes conduct, mood, or energy that is intensely, often almost uncontrollably, excited. In everyday use, a manic grin or manic energy suggests exuberance, frantic activity, or a person who will not slow down; the tone can be admiring, playful, or mildly critical. As a noun, it can mean an extremely excited person, a use that is less common and may sound derogatory. In clinical language, manic has a narrower meaning, referring to the abnormally elevated or irritable mood and increased activity associated with mania, especially within a manic episode. The distinction matters because manic is not itself a complete diagnosis: clinicians assess the duration, severity, and pattern of mood symptoms, and bipolar disorder is only one possible diagnosis. The word is therefore useful for describing both emotional excess and a recognized psychiatric phenomenon, while its figurative senses often carry suggestions of speed, intensity, and lack of restraint.
Wildly excited, energetic, or frenzied; in clinical use, characterized by or relating to mania.
"A manic grin spread across his face as the opening act began."
The figurative sense is common in informal English. In psychiatric contexts, the adjective describes features of mania rather than serving as a diagnosis by itself.
A person characterized by extreme excitement or uncontrolled behavior; less commonly and in dated clinical usage, a person experiencing mania.
"He was the sort of manic who never sat still."
This noun use is uncommon, can sound derogatory, and is less frequent in modern psychiatric writing than the adjective.
To make manic or wildly excited.
"The relentless strobe lights manicked the crowd into a frenzy."
This is a rare verb form; the adjective and noun uses are much more common.
The standard plural is manics, although maniacs is more familiar in general use. The clinical noun use is now dated and may be considered derogatory.
"The documentary portrays several manics, though it reflects an older style of psychiatric language."
One Greek root gave English both madness and frenzy: the source of manic, maniac, and monomania.

Where does manic come from?
Manic entered English in the early 17th century from French maniaque, from Latin maniacus, and ultimately from Greek maniakos, meaning mad or insane. This was derived from mania, meaning madness or frenzy, which is conventionally related to the Greek mainesthai, to be mad. The same root underlies mania, maniac, maniacal, and monomania.
